Compressor specification

A conveying line inlet air velocity, Ci, will need to be specified for the given material and conveying conditions, and a pipeline bore, d, will also need to be evaluated. By re-arranging the above equations and substituting for constants (including R) and free air conditions it can be shown that  

This is the volumetric flow rate of air required for conveying the material through the pipeline. To this may need to be added an allowance for any leakage of air across the 

The air supply pressure to be specified will be pi plus allowances for any pressure drops, such as that between the compressor and the material feed point into the pipeline. 

It should be emphasised that absolute values of both pressure and temperature must always be used in all of the above equations.
